@nicky508 would you please have another look? I fixed the styling and I notice that the coverage report is not being produced.

Take a look

I think I've found probably some error. I am not able to build the the stuff because I got this weird sign everywhere in the code "Ã". I removed them but the test still do not run since I got this outcome:

{DEFAULT_OUTPUT__synthetic0.api.json={
    "steps": [
        �FOR block:blocks SEPARATOR ","�
            �block.step�
        �ENDFOR�
    ]
}
}

Looks like this weird sign again. I am not sure where this sign is coming from.
